Definitions

  • the present invention relates generally to communication quality levels in a radio communication system, such as a cellular communication system. More particularly, the present invention relates to apparatus, and an associated method, for facilitating controlled degradation of a QoS (quality of service) level parameters during a communication session in the radio communication system if a desired QoS level parameter is unable to be maintained.
  • a QoS quality of service
  • a storage register stores a service degradation profile.
  • the service degradation profile includes an indication of one or more degraded QoS level parameters to be maintained in the event that a desired QoS level parameter is unable to be attained or maintained during a communication session. If the desired QoS level parameter of ongoing communication session is unable to be maintained, an attempt is made to effectuate or continue communication at a reduced-quality degraded QoS level parameter corresponding to a degraded QoS level parameter stored as part of the service degradation profile.
  • the service degradation profile When implemented in a cellular communication system, the service degradation profile forms part of a service subscription plan and is stored at the HLR (home location register) associated with the mobile station. If, during initiation of communications or during ongoing communications, such as when a hand off between base stations is attempted, communications at the desired QoS level parameter cannot be achieved, a degraded QoS level parameter stored as part of the service degradation profile is accessed. Communications with the mobile station at the degraded QoS level parameter is attempted. Service renegotiation with the mobile station is not required as the service degradation profile is automatically accessed and communications are effectuated, if possible, at the degraded QoS level parameter. Thereby, system overhead, such as control signaling between the network and the mobile station, is reduced. When communication conditions require that the QoS level parameter of communications with the mobile station be reduced, the service degradation is implemented in a controlled and non-abrupt manner.
  • a communication system permits the communication of information between a sending station and a receiving station and is formed, at a minimum, of a transmitter, located at the sending station, and a receiver, located at the receiving station, interconnected by a communication channel.
  • Communication signals are formed of the information to be transmitted by the sending station.
  • Communication signals are formed to be of characteristics to permit their transmission upon the communication channel.
  • the receiving station is tuned to receive the communication signals transmitted upon the communication channel. Information contained in the communication signal transmitted upon the communication channel is recovered, once received at the receiving station.
  • a radio communication system is a communication system in which the communication channel upon which the communication signal is transmitted is formed of a radio channel defined upon a portion of the electromagnetic spectrum. Because a wire line connection is not required to form the communication channel between a sending and a receiving station, communications are possible when such a wire line connection between the sending and receiving station would be impractical.
  • a cellular communication system is exemplary of a radio communication system.
  • Cellular communication systems constructed according to various standards, have been installed throughout significant portions of the world.
  • a subscriber to a cellular communication system is able to communicate therein by way of a mobile station when the mobile station is positioned within an area encompassed by the communication system. Telephonic communication of both voice information and data information is permitted in such networks.
  • Access to communication by way of the cellular communication system is permitted pursuant to a service subscription to which a subscriber subscribes.
  • a unique identification number is associated with the service subscription.
  • the identification number is used in authentication procedures to provide a mobile station, operable pursuant to the service subscription, access to the cellular network.
  • the identification number is also used for billing purposes.
  • QoS (quality of service) level parameters can be defined to provide a standard by which to measure or ensure minimum communication quality levels.
  • a QoS level parameter can be used in service initiation and service modification.
  • a QoS level parameter defines a communication quality level in terms of, e.g., a data transmission rate, a bit error rate, or a signal delay amount upon a forward link and upon a reverse link.
  • the QoS level parameter must be met to ensure an appropriate level of communication quality, defined by the values of the parameters associated with the QoS level.
  • the QoS level parameters might not be able to be achieved during a particular communication session.
  • Such parameters may not be able to be achieved during service initiation during which the communication session is attempted to be initiated, or during the communication session, such as when a hand off is requested or otherwise attempted.
  • the desired QoS level parameters may not be able to be attained or maintained due to lack of resources available for the communications during the communication session. If the desired QoS level parameters cannot be attained or maintained, there might be a service renegotiation between the network infrastructure and the mobile station which requires significant levels of control signaling between the mobile station and the network infrastructure and also within the network. Such control signaling is referred to as overhead as the signaling requires system resources without directly providing user communications.
  • the present invention accordingly, advantageously provides apparatus, and an associated method, for facilitating controlled degradation of QoS level parameters of communications in a radio communication system, if communications at desired QoS level parameters are unable to be effectuated or maintained.
  • a service degradation profile is stored in a storage register.
  • the service degradation profile is associated with a mobile station operable in a radio communication system.
  • the service degradation profile includes one or more degraded QoS level parameters at which to attempt to effectuate or maintain communications in the event that desired QoS level parameters cannot be achieved. If the desired QoS level parameters cannot be achieved, an attempt is made to communicate at QoS level parameters corresponding to the degraded QoS level parameters stored as part of the service degradation profile.
  • the communication in the event that the communication cannot be effectuated or maintained at a desired QoS level parameter, the communication shall be effectuated or continue at the degraded QoS level parameter without the need for control signaling with the mobile station and within the infrastructure to renegotiate service quality levels.
  • the service degradation profile is implemented in a cellular communication system, such as a cellular communication system conforming to the standards set forth in the IS-95 3G specification promulgated by the EIA/TIA.
  • the service degradation profile is stored together with other subscriber profiles at the HLR (home location register) associated with the mobile station. If communication cannot be effectuated or maintained at desired QoS level parameters, the service degradation profile is accessed, and communications are effectuated or maintained, if possible, at the degraded QoS level parameters stored as part of the service degradation profile. Service renegotiation with the mobile station is not required as the service degradation profile is automatically accessed. And, because the service degradation is implemented pursuant to a prescribed service degradation profile, abrupt service degradation of communications with the mobile station are less likely to occur.
  • apparatus, and an associated method for reducing a desired QoS (quality of service) level parameter of communications between a mobile station and a fixed network of a radio communication system.
  • the fixed network includes a plurality of spaced-apart, fixed-site transceivers positioned throughout a geographic area. Each fixed-site transceiver defines a coverage area in which communications with a mobile station are permitted pursuant to a service subscription.
  • the desired QoS level parameter is reduced to a selected degraded QoS level parameter when communications pursuant to at least a first communication service at the desired QoS level is unavailable.
  • a service subscription register is associated with the mobile station.
  • the service subscription register stores an indication of at least a first selected degraded QoS level parameter at which the communication pursuant to the at least the first communication service are to be maintained if the continued communications at the desired QoS level parameter are unavailable.
  • a resource availability determiner is coupled to receive information representative of at least the first selected degraded QoS level parameter when the communications at the desired QoS level parameter are unavailable.
  • the resource availability determiner and service level selector selectively determines the availability of resources of the radio communication system and selects service levels to assure that the communications are available at least at the first degraded QoS level parameter.

  • a Communication signal transmitted by a base stations 16 to a mobile station is transmitted upon a channel referred to as a forward link, and a communication signal generated by the mobile station and transmitted to a radio base stations 16 is transmitted upon a communication channel referred to as a reverse link.
  • the base stations 16 are positioned at spaced-apart locations throughout the geographical area encompassed by the communication system 10 in manners such that the two-way coverage areas by which the cells 14 are defined at least partially overlap with one another.
  • the base stations 16 are positioned at the centers of their associated cells 14 .
  • base stations utilizing sector antennas are sometimes utilized so that more than one base station may be co-located and cells associated with the base station are defined by the sectors of coverage of such sector antennas.

  • Cellular communication systems make efficient use of the portion of the electromagnetic spectrum allocated for communications therein. Because of the spaced-apart nature of the base stations, the communication signals transmitted between the mobile station and a base station 16 located proximate thereto need only be of a relatively low power level. Because of transmission of the communications signals at such relatively low power levels, the same channels may be re-used at various cells of the system according to a channel allocation scheme. Thereby, a relatively large number of concurrent communications can be effectuated within a limited bandwidth allocation.

  • a separate priority level is associated with each service-type. For instance, service subscription can be made for audio service, web page browsing service, and video-on-demand service, all pursuant to a single service subscription. A separate priority level is associated with each of such three service-types.
  • the priority level defines a priority-of-access representing the priority to be given to the mobile station operable to the service subscription to communicate in the radio communication system pursuant to the service-type.
  • the priority level pursuant to which subscription is made for the particular service-type is used to allocate the system resources to the mobile station having the higher priority level associated therewith.
  • the priority level 162 defines a default priority for the audio service-type of the profile shown in FIG. 6 .
  • the default priority can be overwritten on a per-call basis by a user during service initialization, either for a mobile-originated or a mobile-terminated call by way of L3 signaling. That is to say, a priority parameter can be entered to overwrite the default priority.
  • a mobile-terminated call uses the default priority level, such as the level 162 , together with an option for the subscriber to change the priority upon receipt of the call at the mobile station.
  • the priority parameter used to overwrite the default priority is maintained by the system until the call is terminated.
  • Resource contention procedures are instituted, for instance, when competing subscribers simultaneously request limited resources during service initialization or when service modifications require that additional resources be allocated to a communication session. Resource contention also occurs when a handover is to be effectuated to a new cell at which new resources need to be allocated to the communication session. Also, resource contention procedures are required when a subscriber, that has been downgraded, and before service is upgraded through a previously-requested service level subsequent to renewed availability of the resources. For example, if a subscriber requests audio-only service with the highest priority, resources will be allocated to such subscriber before another subscriber is granted resources with a lower priority. The unfulfilled service is downgraded based upon the parameters of the service degradation profile.
  • QoS prioritization occurs when, even when the system is operated at full capacity, an emergency call is made.
  • An emergency call given a highest priority, will cause a lowest-priority call to be dropped to ensure that the emergency call is effectuated.
  • Remaining portions of the service degradation profile 32 shown in FIG. 6 correspond to commonly-referenced portions of the profile 32 shown in FIG. 2 . Description of such other portions of the profile 32 is as above-described.
  • FIG. 7 illustrates a method, shown generally at 182 , of the method of an embodiment of the present invention.
  • the method reduces a desired QoS (quality of service) level of communications between a mobile station and a fixed network of the radio communication system. The reduction is to at least a first selected degraded QoS level when continued communication pursuant to at least a first communication service at the desired QoS level is unavailable.
  • an indication of at least a requested QoS level is stored. Alternately, a default QoS level indicated in the SDP profile can instead be stored.
  • the stored level is a level at which communication pursuant to the at least the first communication service are to be maintained, if possible.
  • the yes branch is taken to block 192 , and the communication session is continued. A determination is then made at the decision block as to whether there has subsequently been degradation of the QoS level of communications. If not, the no branch is taken back to the block 192 ; otherwise the yes branch is taken back to the block 186 .
  • system overhead required for service renegotiation when parameters of a desired QoS level cannot be attained or maintained is reduced. Also, because service degradation is effectuated pursuant to a service degradation profile, abrupt termination of a communication session is less likely to occur if the parameters of the desired QoS level cannot be assured.
